MULTIPLE-FUSE CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 463,764, dated November24, 1891.

Application filed November 26,1890- Serial No. 372,701. (No model.)

To all whom itmay concern: 7

Be it known that I, GEORGE K. WHEELER, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois, haveinvented a certain new and useful Im provement in Multiple-Fuse Cut-Outs, of which the following is a specification.

My present invention relates to an improved form of multiple-fusecut-outs; and it aims to 10 provide a simple, compact structure, easilyand cheaply manufactured, by which a number of fuses may be successivelyinserted into the electric circuit which requires protection, so thatwhen one fuse is ruptured another may be quickly introduced to take itsplace and the ruptured one may be removed without danger of shock to theattendant. These improvements are illustrated in the accompanyingdrawings, wherein Figure 1 is aplan view, and Fig. 2 a sectional view,taken through one of the circuitterminals.

In the views, A is a base-piece, which represents simply a means ofattachment for the cut-out. Pivoted to this block upon a spin- -dle B isa disk of insulating material Csuch as hard rubber, glass, orporcelainwhich serves as a support for the fuses. Around the edge of thedisk are set a number of 0011- tact-pieces D, suitably secured thereto,which project a short distance beyond the circumference of the disk,as'is seen in Fig. 2. The fuses, of which any desired number may beused, are seen at E and have jaws E, by which they are secured to thecontacts by setscrews F.

The circuit-terminals G are secured to the base-piece A or other supportand are arranged in the arc of a circle concentric with the spindle B,so that as the disk is turned the different contact-pieces D aresuccessively brought into engagement with them. These terminals areshown in Fig. 2 grooved or cut away, as at cl, to receive the projectingends of the contact-pieces and insure a good electrical connection.

A suitable handle I is provided upon the disk, and, as will be readilyunderstood,whenever one fuse is ruptured it can be moved one made totake its place by simply rotating the disk. The ends of the rupturedfuse can then be removed without danger to the atteu dant, and a new onecan be attached at his leisure withoutinterruption of the circuit whichthe fuse protects.

In designing the fuse described above I have had more particularly inmind its application to railway service; but it will be found equallyadvantageous upon other self in this respect.

hat I claim as new, and desire to secure by Letters Patent, is

1. A multiple-fuse cut-out comprising a pivoted rotary'disk ofinsulating material, contacts arranged around the edge of the disk onone of the flat faces thereof, fuses attached to said contacts, and apair of circuit-terminals making connection with the contactsin pairs asthe disk is rotated.

2. The combination, in a multiple-fuse cutout, of the pivoted rotarydisk of insulating material, separate sets of contacts arranged aroundon the edge of one of the fiat faces of the disk, fuses arranged aroundsaid disk in circular form and secured to the contacts, andcircuit-terminals in the path of travel of the contacts, whereby thefuses may be inserted in circuit successively by rotating the disk, asset forth.

In witness whereof I have hereto set my hand this 7th day of November,1890.
